Solving Problems
With the Serial
Web Utility
If you are unable to connect to the hub’s web interface, it may be that:
■
The hub is not turned on.
■
You are not using a proper null modem cable, refer to “Examples of
Null Modem Cables You Can Use” on page A-4.
■
The following settings are different on your hub and management
station:
■
Flow control.
■
Speed (baud rate).
■
The hub has automatically configured its communication speed, but
you have subsequently changed the speed configured on your
management station (the device only automatically configures the
speed the first time it connects).
■
You have selected the wrong COM port on your management
station.
To change some of the settings for the management station, use the
Advanced Configuration Parameters dialog box. To display this, select
the Serial Web Setup program item in the Serial Web program group.
